4.2 Code Example: Controlling Servo Motor Direction: To control the direction of the servo motor using Arduino, the following code snippet can be used: #include <Servo.h> Servo myServo; void setup() { myServo.attach(9); // Attaches the servo to pin 9 } void loop() { // Rotate the...

Without further ado, let us jump right in on how to control a DC motor using an Arduino Motor Shield. Why can the DC motor rotate? That’s because of the left-hand rule. When the current flows through the rotor, the rotor generates a force in the magnetic field, which can rotate. ...
bridge is used to rotate motor either in clock wise or anti clock wise direction. So the main advantage of servo motor is that it doesn’t require any interfacing circuit. However, the main disadvantage of servo motor is its lower speed and low power limitation as compared to other motors....
Once you upload this code, you can open the Serial Monitor at a baud rate of 9600 to see the movement of the encoder change as you rotate it. Troubleshooting If the encoder values are erratic or do not change as expected, double-check your wiring against the schematic and ensure that you...

The eagle-eyed amongst you may have noticed that the “alert bell” in the corner of the Thing page turns red when you add cloud variables. This is because the IoT Cloud has auto-generated code to go with each of them. The second tab on the Things page is the Sketch tab. If you ...
